Headrest Height Adjustment

Hold the handle of headrest to adjust the height of it.There are 5 positions with 1.97" range.

The most suitable height could be achieved when one's scruff is fully supported by the headrest.

Headrest Angle Adjustment

Hold the headrest cushion to adjust the angle of it.There is 120o range adjustment.

The best angle could be reached when one could move the neck naturally.

Backrest Tilt Angle Adjustment

Pull the single rod control lever completely backward and lean against back until a desired angle is achieved,and then return the lever to the original middle position to lock at an ideal angle.There are 4 positions with 25º range.

The proper backrest angle can reduce the pressure on the spine.

Backrest Quick or Slight Tilt Tension Adjustment

Pull the lever outwards,open the tilt tension adjustment handle, and turn it forward or backward into a desired tension for quick tilt tension adjustment or close the handle and turn it forward or backward for slight tilt tension adjustment,and then close the handle and push the lever inwards to the original position to fix it.

The synchro mechanism is ergonomically designed to enhance comfort and reduce strain.The back-to-seat adjustment/tilt is 3:1 ratio.

Backrest Height Adjustment

Lumbar Support Height Adjustment

While sitting and leaning against the backrest,pressing the backrest height lever can change the height of backrest.

A.The height of lumbar support can also be adjusted by pressing the backrest height lever.There are 4 positions locking and the adjustable distance is 2.36". B.Suitable height of the lumbar support would bring more comfort for one's waist.

Seat Height Adjustment

Pull up the single rod control lever and hold it while raising or lowering the seat to change the seat height.When the lever is released,the seat height is locked.

Since a incorrect seat height contributes to back's fatigue,it is recommended that the angle of knees is slightly less than 90º and feet are level with the floor.

Seat Depth Adjustment

Push the single rod control lever forward to adjust the seat depth (The approximate range is 1.97"). When the pull is released,the position will be fixed.

Ideal depth is achieved when the upper legs are on the seat,the lumbar area is in touch with the backrest of the chair,and the back of knees does not touch the edge of seat cushion.

Armrest Height Adjustment

Press the two-side armrest height adjustment buttons to raise or lower the armrests.There are 8 positions with 3.15" range.

Recommended armrest position: Allow arms to rest comfortably on the armrest at a 90º angle while the armrest is 1" higher than the elbow.
